Gerbera daisies

(Question)

I live near Newmarket ON and planted red gerbera daisies. Once the initial blooms were done I have not seen any new buds, suggestions?

(Answer)

I am glad you asked, because I’m in the same boat as you!  I too have a couple of the daisies in my window boxes, and I’m not spying any new blooms as the old ones die, even though I deadhead (pinch off the dead flowers to encourage new blooms).

Here’s some basic information on care of gerbera daisies, which are native to South Africa:

  • Plant them with the crown [i.e., where the stem and roots meet] at or slightly above the soil level;
  • Plant in full sun, in well-draining soil;
  • Don’t crowd them together – plant them 30-45 cm (12-18 inches) apart;
  • The plants like a uniform moisture level, and mulching around the plants might help achieve this (but make sure you do not bury the crown).  However, let the crown dry out between waterings;
  • If the soil is too moist, this can lead to root and stem rot;
  • Fertilize the plants regularly – gerberas are prone to iron and manganese deficiency, so make sure the fertilizer you use contains these nutrients

With time, the daisies tend to sink into soil, so the crown is at risk of becoming covered; it’s appropriate to lift out and replant the gerberas from time to time. I think this is what mine need!
